Year of the Dragon King Slot by Pragmatic Play

The central mechanic replaces traditional free spins with something genuinely different. On any base game spin, random reels can change their background to green, blue, or red. When all five reels match the same color, the Mini Slot Machine bonus activates. One to five miniature slot machines then appear directly on the grid, each operating independently with its own spins and payouts.

These mini slots are simple three-reel, single-payline machines that land blanks or colored 8s. Any line of matching 8s pays - blue 8s award 2x, yellow 8s 5x, and red 8s 20x your bet. Each winning spin on a mini slot earns another spin on that machine. A losing spin locks it out permanently, and the round ends when every mini slot is locked. The more mini slots active at once, the longer the feature runs and the higher the potential payout.

Four buy bonus options at 60x, 100x, 140x, and 350x let you skip the random color-matching trigger entirely. The price tiers correspond to different bonus configurations - higher buy-ins presumably guarantee more mini slot machines or better starting conditions. An ante bet option bumps your stake by 50% for improved trigger frequency in the base game.

The visual treatment goes full Chinese New Year: misty mountain summit at sunset, red pillars framing the grid, gold coins and paper lanterns as premium symbols. The mini-slot mechanic feels distinct from standard bonus rounds, though the 5,000x cap keeps the ceiling modest for a very-high volatility game.
